@a QM ATTORNEY or the other oi tine hears be raised independently ci theother. by connecting ,the clutch ifi, the beam be raised horiaon tallyfrom either end of the trame by mereiy applying a cranls to one oranother oi the shafts se. To permit a patientto rest with ease orwithout being subjected te unnecessary shock. or vibration while transpoted, springs Mib may be interposed between the nuts it and the ends lilaof the beam The beam, as alreadystatecl, is a lifting beam and carries aplurality of hangers le which are square in cross section to preventswinging movement about the beam, but they are slidable longitudinallyof the be. .Each hanger carries a pair of supporting arms le pivoted tothe hanger as at il. The arms normally assume the dotted line positionshown at No, see Fig. 4, but they may be swung downwardly andy inwardiyas shown in full lines in Fig. 4.

The shape of the arms is clearly disclosed in Fig. 2. That is, they arechannel-shaped at their upper ends to provide 'strength and they aregradually flattened and rounded at their lower ends so that they may bereadily pushed in under or inserted between the patient -and themattress upon which he or she is lying so as to be in a position tosupport a person when the beam B is lifted. The arms, as already stated,normally assume the dotted line position shown at l6a as springs ib areinterposed between the hanger and each arm to normally maintain them lna sufiiciently spread position to clear the patient when they arelowered to pick up the patient. A pocketle is formed at the lower end ofeach arm, and these may be lled with warm water, or a hot water bag oran electric heating pad or the like may be inserted in the pockets toheat or warm the arms prior to use.

In actual practice, if it Yis desired to remove a' patient from his orher bed, the frame is placed in a position straddling the bedlengthwise, as

shown in Fig. l. When the frame is first brought into position, thesupporting arms I8 will assume their spread position. Each arm is theninserted in under the patient orbetween the patient and the mattress,and when inserted are locked one by one by pins ld which are inserted atthe saine time through the hangers and the inner upper ends of the armsto lock them and secure them against pivotal movement, thiis preventingaccidental spreading tient is being lifted and wnile supported by thearms. In this position, the beam B and hangers supporting the patientare elevated and the frame may be swung clear of the vbed and may beshoved or pulled from room to room. By this construction andarrangementof parts, it becomes possible for a single person orattendant to pick up a patient and transport the patient from room toroom, as when the frame straddles the bed and the beam and arms arelowered to pick up the patient, the nurse will first stand on one sideof the bed and insert one arm after the other under that side of thepatient and lock them and can then step around to the other side of thebed and insert the arms on that side and iock them, and then eitherapply a hand crank or power to one or more of the shafts 8a and elevatethe patient with relation to the bed, after which the frame carrying thepatient may be readily shoved or pulled wherever desired.

When the patient is to be released, for inwards, the inward movement iand vertically movable in the frame, means of the arms while the pa-`afi-eases stance to be placed upon an operating table or another bed,the frame Ei is lowered until the patient rests on the bed and tne armsie are then removed one by one. The entire operation of raising and.lowering the patient and transferring the patient from place to place isthus simply andreadily accomplished and without any exertion onthe partoi the nurses or attendants, and, furthermore, without shock, vi brationor inconvenience to the patient.

The supporting arms it are, as previously stated, pivoted at il, and assprings are inter-s posed between the arms and the hangers, the armswill normally assume a spread position, but their inward movement willbe limited as the ends ite of the arms will engage extensions iia of thehangers and thereby` prevent any squeezing or application of pressure tothe patient when supported by the arms. In other limited by theextensions lea and ite. The arms are arranged in pairs wherever the bodyis to be supported, but a single arm will suffice for the head, and thisarm is indicated at i9.

While this and other features of the present invention have been more orless specifically described and illustrated, I wish it understood thatvarious changes may be resorted to within the scope of the appendedclaims, and similarly, that the materials and finish of the severalparts employed may be such as the manufacturer may decide or varyingconditions or uses may demand.

Having thus described my invention, what I claim and desire tesecure byLetters Patent is:

1. In a lifting device cf the character described an elongated frame, alifting beam guided and vertically movable in the frame, a plurality ofhangers movable longitudinaiiy of the beam, a pair of arcuate supportingarms independently pivoted to each hanger, a spring interposed betweeneach ariril and hanger to normally maintain the arms spread apart, meansfor limiting the movement of the arms towards each other, and aresilient support for each end of the beam.

2. In a lifting device of the character described an elongated frame, alifting beam guided for lifting both or either end of the beam to causeit to assume a horizontai or an angular position within the frame, aplurality of hangers. on the beam, a pair of arcuate supporting armsindependently pivoted to each hanger, a spring interposed b-etween eacharm and hanger to normally maintain the arms spread apart and in araised position, means for limiting the movement of the arms towardseach other, and a resilient support for each end of the lifting beam.

3. In a lifting device of the character described, having a main frameand a lifting beam guided and vertically movableE therein, a pluralityof hangers on the lifting beam, a pair of arcuate supporting armsindependently pivoted and movable on each hanger, a spring interposedbetween each arm and hanger and normally maintaining each arm in araised position and spread apart. said pivots and springs permittingeach arm to be independentiy swung from a raised to a lowered position,and means for locking each arm against pivoting movement when swung to alowered position.
